Dear Michelle:

Why can't my daughter manage her life better? She is 17 and an honor student, but she seems to be wasting her life away with a boyfriend who is holding her back.

He consumes every waking, minute of her precious time and smooth-talks her as well.

His goal is to get her to agree to go to the college of his choice, not her choice, and because his grades are lower, his choice will be limited.

I feel like I want to rescue her, but she pushes me away and shuts me out. She has only brought us pride and joy; and now this! Help!

A worried mother

Dear Mother of a 17-year-old Girl:

Hmmmmm. What's the matter with kids today? Remember that song from "Bye Bye

Birdie"?

Well if you do not, let me fill you in about teenagers and their life-management skills.Do not expect too much too soon because at the ripe age of 17, life-management is not within their reach, not should it be.

Life experience creates both the conditions and the skills for management, and if management went before experiene, there would be tittle of it.

Your daughter is an honor student for good reasons. She is smart, studies with

intelligence and you have given her good Values.

When the time comes for her to apply for college, and she visit the ones that were specifically desigened for student the top of their grade, she will most likely break away from her boyfriend's influenee.

It is rare for an honor student to change the path of their academic career for puppy love. That being said, them might be some adoldscent wisdom in her behavior after all.

Perhaps she is choosing to worry you, her parents, for unconscious reasons. Being such a good girl and being a steady source of joy might have become a bit too much for her.

Let your daughter have her own private moment of 11^th grade rebellion. She deserves a break from perfection.

“The world’s oceans are slowly getting more acidic．” say scientists．The researchers from California report that the change is taking place in response to higher levels of carbon dioxide in the atmosphere．

The lowering of the waters’ pH value is not great at the moment but could cause a serious threat to current ocean life if it continues, they warn．Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature．Increasing use of oil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater．Once in the water, it reacts to form carbonic acid．Scientists believe that the oceans have already become slightly more acidic over the last century．

These researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change．“This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere,” said Dr Caldeira．“And we predict the amount of future acidity will exceed（超过） anything we have seen over the last several hundred million years, let alone perhaps after rare disastrous events such as asteroid（小行星） impacts．

However, it is not absolutely clear what that means for ocean life．Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean life forms may be more sensitive to pH changes．Coral reefs（珊瑚礁） and other organisms whose shells contain calcium carbonate（碳酸钙） may be particularly affected if the water’s acidity levels keep going up, the team predict．They could find it much more difficult to build these structures in water with a lower pH．

In recent years some people have suggested storing carbon dioxide from power station in the deep ocean as a way of dealing with global warming．But Dr Caldeira said that such a strategy should now be re-considered．“Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing --- because in releasing CO2 into the atmosphere we warm the planet, and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming．”

The ocean is becoming more acidic due to __________．

A．the higher level of CO2 in the air B．the warming atmosphere

C．the increasing use of oil fuels D． the lower water pH value

According to Dr Caldeira, __________．

A．more oil fuels will be used in the near future

B．ocean absorption of carbon dioxide is a good thing

C．the future situation of the amount of acidity is extremely serious

D．scientists may predict climate changes with computer models

If the water’s acidity level keeps rising, __________．

A．the waters’ pH value will become higher and higher

B．some disastrous events will occur more often than before

C．organisms living near the surface are more sensitive to pH changes

D．ocean life whose structures contain calcium carbonate may be affected

Most experts once believed storing carbon dioxide in the ocean would reduce __________．

A．the CO2 absorbed by the ocean B．the amount of greenhouse warming

C．the acidity of the ocean D．the gradual release of CO2

The purpose of this passage is to __________．

A．show people the findings of a research team

B．introduce Dr Caldeira and his team’s research

C．warn people of the higher level of CO2

D．inform people of how acid the ocean is now

One day, when I was in high school, I saw a kid named Kyle walking home from school with all his books, I thought to myself, “ 11 would anyone bring home all his books for the weekend? He must really be 12 .” As I was walking, I saw several kids running toward him. They ran at him, 13 all his books out of his arms and he fell down in the dirt. His glasses went 14 and landed in the grass.

My heart went out to him. So, I ran over to him. 15 I handed him his glasses, he looked at me and said, “Hey, thanks!”

I helped him pick up his books, and asked him where he lived. As it 16 , he lived near me. We talked all the way home. Over the next four years, Kyle and I became best friends.

Kyle was the 17 student of our class, one of those guys that really found themselves during high school. Therefore he had the 18 to prepare a graduation speech. On the graduation day, I could see that he was 19 . So, I patted him on the back and said, “Hey, big guy, you’ll be great!” He looked at me and smiled.

He cleared his throat, and began. “Graduation is a time to 20 those who helped you make it through those 21 years. Your parents, your teachers… but mostly your friends, I am here to tell all of you that being a friend to someone is the best 22 you can give him.”

I just looked at my friend with disbelief as he told the story of the first day we met. He had planned to 23 himself over the weekend and was carrying his books home. “Thankfully, nothing happened. My friend 24 me from doing the unspeakable.”

Not until that moment did I realize that you should never underestimate(低估) the 25 of your actions. With one small gesture you can change a person’s life. For better or for worse.
